A brochure is a physical or digital document used to test your value proposition directly with customers. To prepare a brochure, you should define your value proposition, solution specifications, and target customers. Once these are clear, you can create your brochure. For execution, present the brochure to customers with one team member conducting the interview and another taking notes on customer quotes, jobs, pains, gains, and body language. Afterward, wrap up the interview and analyze your notes with the team.
